带电作业人员侵入110kV电缆终端塔间隙方式对套管及应力锥电场分布的影响研究
Dianci bileiqi, 2022 电缆终端套管是电缆线路的薄弱环节，为了掌握带电作业人员不同侵入电缆终端塔间隙的方式对套管及其应力锥电场分布的影响，根据实际110 kV电缆终端搭建仿真模型，因电缆终端塔和应力锥的尺度差异大采用子模型法来优化计算模型，分析了电缆终端正常运行及带电作业人员处于地电位作业、中间电位作业以及等电位作业3种情况对电缆终端应力锥电场分布的影响。计算结果表明：子模型法在保证计算精度的条件下可以有效减少网格数量和缩短计算时间；应力锥在3种作业方式下的电场变化相对于正常运行时均在3.5%以内 ...
